    PATCH-9_9-gta01-Tweak-pixclock-to-reduce-flicker-with-cpufreq.eml
    
    Experimenting with a GTA01 showed pixclock values near 40000 (after the
    rounding caused by the divider calculation) caused visible flicker. Values
    near 20000 caused only a slight flicker, and the default value after rounding
    with the default HCLK frequency of 133MHz is 30075.
    
    Change the value to 35000 to make it stay in the range 17500-35000 and thus
    reduce the flicker a bit.

    PATCH-7_9-Experimental-S3C2410A-cpufreq-driver-serial-.eml
    
    This is the cpufreq notifier for the S3C2410 serial driver.
    
    It uses the hardware flow control, when available, to avoid losing characters
    during the transition.

    PATCH-6_9-s3c2410-serial-move-divisor-calculation-to-separate-function.eml
    
    The cpufreq notifier for the S3C2410 serial driver has to recalculate the
    baud rate divisor. The code which does the calculation is currently part of
    s3c24xx_serial_set_termios. Split it off to a separate function.
    
    Code movement only, no functional changes.

    PATCH-3_9-cpufreq-Warn-whem-cpufreq_register_notifier-called-before-pure-initcalls.eml
    
    If cpufreq_register_notifier is called before pure initcalls,
    init_cpufreq_transition_notifier_list will overwrite whatever it did,
    causing notifiers to be ignored.
    
    Print some noise to the kernel log if that happens.

Date:   Mon Jul 21 00:55:46 2008 +0100

    PATCH-2_9-Experimental-S3C2410A-cpufreq-driver-core-.eml
    
    This is a cpufreq driver for the S3C2410A. It deals only with the main
    frequency switching part and with the SDRAM refresh counter. The rest of the
    hardware should be dealt with via cpufreq notifiers on each of the drivers.
    
    It also has experimental support for the S3C2442.

    PATCH-1_9-cpufreq-fix-show_trans_table.eml
    
    Fix show_trans_table when it overflows PAGE_SIZE.
    
    * Not all snprintf calls were protected against being passed a negative
    length.
    * When show_trans_table overflows, len might be > PAGE_SIZE. In that case,
    returns PAGE_SIZE.

    debug-add-glamo-drive-strength-module-param.patch
    Suggested-by: Werner Almesberger <werner at openmoko.org>
    
    This patch allows users to control two additional settings
    in Glamo MCI driver from kernel commandline or module
    parameters.
    
    
    First is Glamo drive strength on SD IOs including CLK.
    This ranges from 0 (weakest) to 3 (strongest).
    
    echo 0 > /sys/module/glamo_mci/parameters/sd_drive
    
    (Changes to this take effect on next SD Card transaction)
    
    or, from kernel commandline
    
    glamo_mci.sd_drive=0
    
    On tests here with 0 strength, communication to SD card
    (shipped 512MB Sandisk) seemed fine, and a dd of 10MB
    urandom had the same md5 when written to cache as after
    a reboot.  I set the default to 2.
    
    
    Second is whether we allow SD_CLK when the SD interface
    is idle.
    
    # stop the clock when we are idle (default)
    echo 0 > /sys/module/glamo_mci/parameters/sd_idleclk
    
    # run the SD clock all the time
    echo 1 > /sys/module/glamo_mci/parameters/sd_idleclk
    
    (changes take effect on next SD Card transaction)
    
    From kernel commandline, eg:
    
    glamo_mci.sd_idleclk=1
    
    Normally you don't want to run the SD Clock all the time.

    debug-move-dev-info-to-dbg.patch
    Suggested-by: Sean McNeil <sean at mcneil.com>
    
    To see if some subtle race is involved, Sean has tried
    removing syslog traffic during resume and found he was
    not seeing the resume crash any more.  We're giving it
    a try to see if it changes the behaviour for anyone
    else.  It would mean we have a pretty fine race in there
    somewhere.
